Public bug reported:
When I boot into my system, an ASUS Zenbook UX31, the elantech touchpad
works fine. I have a small script to configure it which is run when my
session starts, and those parameters are applied fine without problem.
Here is the script, in case something in there might be relevant :
#!/bin/sh
synclient FingerLow=9 FingerHigh=12
synclient MinSpeed=2.0 MaxSpeed=4.0 AccelFactor=0.1
synclient VertTwoFingerScroll=1 HorizTwoFingerScroll=0
synclient CoastingSpeed=10 CoastingFriction=25
synclient TapButton1=1 TapButton2=3 TapButton3=2
synclient EdgeMotionMinZ=30 EdgeMotionMaxZ=40 EdgeMotionMinSpeed=100
EdgeMotionMaxSpeed=400
synclient PalmDetect=1 PalmMinWidth=5 PalmMinZ=1
#must restart syndaemon to set those params.
killall syndaemon
syndaemon -i 1 -t -K -d
The issue is that after a while, the multitouch just stops working. I am
still able to use the touchpad, but it cannot scroll with two fingers, I
cannot tap with two-three fingers to right-middle click, it's all gone.
I haven't been able to pinpoint the exact issue yet.
I have also encountered this issue with the 3.4.0-rc6 kernel.
In 11.10, everything ran smoothly, and I never encountered this issue.
